Frequently asked questions

What is File encryption?

Encrypt or decrypt any file with a password (AES-256).

When would I actually use this?

Before sharing something: stripping the location and device data a photo carries, removing the metadata a document keeps, and checking what is actually left behind.

What is the most common mistake?

Assuming a screenshot is anonymous. It carries the interface around the content — names, timestamps, notification previews and account details in the corners — and those are read as readily as the part you meant to share.

What else is filed next to it?

EXIF metadata cleaner, Django Secret Key Generator and Password generator share its section. They are not variants of it — being filed together is not the same as being alike — but that is where to look if this turned out not to be the tool you wanted.

Where do the figures come from?

Metadata is removed by rewriting the file without those segments — the pixels are untouched, only the tags around them go. What a given format stores varies, and the tool reports what it found before removing it.
